Rani Ki Vav (lit. 'The Queen's Stepwell') is a stepwell situated in the town of Patan in Gujarat state of India. It is located on the banks of Saraswati river. Its construction is attributed to Udayamati, daughter of Khengara of Saurashtra, queen and spouse of the 11th-century Chaulukya king Bhima I. Silted over, it was rediscovered in 1940s and restored in 1980s by the Archaeological Survey of India. It has been listed as one of the UNESCO's World Heritage Sites since 2014.
